不同种植行距和灌水量对中国西北地区日光温室短季节栽培番茄品质的交互影响
Effect of Planting Row Spacing and Irrigation Amount on Comprehensive Quality of Short-Season Cultivation Tomato in Solar Greenhouse in Northwest China
摘要
Abstract
[Objective] The objectives of the study were to investigate the effect of planting row spacing and irrigation amount on the tomato quality cultivated in solar greenhouse in Northwest China,to obtain the best combination of irrigation amount and planting row spacing for the best comprehensive quality,so as to provide a scientific basis and technical guidance for irrigation and cultivation management of greenhouse tomato in the region.[Method] The experiment was conducted in solar greenhouse at the Green Lily fruit and vegetable cooperatives in Yangling Agricultural Hi-tech Industries Demonstration Zone in Shaanxi province.The cultivated varieties of tomato in the experiment was HL2109.The treatments comprised three planting row spacing (L1 (60 cm),L2 (45 cm),L3 (30 cm)),and based on the cumulative evaporation from a 20 cm diameter pan between two irrigations (E),0.6 E,0.8 E,1.0 E,1.2 E were set as four different levels of irrigation amount,when the cumulative evaporation reached (20±3) mm irrigation will be conduct.The treatments were replicated three times in randomized complete block designs.The comprehensive quality of tomato was evaluated by improved fuzzy grey relational method and CRITIC method,respectively.The two evaluation results were compared and multivariate regression analysis was used to find the best combination of irrigation amount and planting row spacing when the best comprehensive quality was obtained.[Result] Tomato quality was affected by both planting row spacing and irrigation amount,and showed a very significant interaction on soluble solids,Vc and lycopene,but the appearance fruit quality indicators of tomato do not exist irrigation amount and planting line spacing between the interaction.Excessive irrigation will reduce the exterior quality of tomato,and reduce the soluble solids,Vc and lycopene content.The results of the improved fuzzy grey relational method and CRITIC method have good agreement with the results of tomato comprehensive quality evaluation,that the L2-0.8E treatment had the best comprehensive quality of tomato,and the L1-1.2E treatment was the worst;the comprehensive quality of tomato followed a downward quadratic parabola shape with the increase of irrigation amount and planting row spacing.Although the proportion of weights for single tomato quality indicators have a little difference between two tested seasons,but the weights of lycopene,Vc and sugar acid ratio are always the first three.[Conclusion] When the ridge distance is 80 cm,planting spacing is 35 cm,the planting row distance selected 37-47 cm,the irrigation quantity is set to 0.8E-1.0E would be the appropriate combination of irrigation amount and planting row spacing for best comprehensive quality of greenhouse tomato in Northwest China.关键词
